Abstract Florida has the most species of introduced and established reptiles in the world. There are more species of non-native lizards reproducing in Florida than native species. Tupinambis merianae (Argentine Black and White Tegu) is established in parts of Hillsborough and Polk counties, FL. No evidence of reproduction has been published in other areas of Florida, although this species has been sighted in various other Florida locations, especially in southeastern sites. Using radio… 
Tupinambis merianae as nest predators of crocodilians and turtles in Florida, USA
The finding that one of the first two crocodilian nests to be monitored was depredated by tegus suggests that tegu should be further evaluated as a threat to nesting reptiles in Florida.
Evidence for an Established Population of Tegu Lizards (Salvator merianae) in Southeastern Georgia, USA
Abstract - Documenting emergence of invasive species in new areas is vital to understanding spatiotemporal patterns of invasions, propagule pressure, and the risk of establishment. Salvator merianae
Observations on Nesting and Clutch Size in Furcifer oustaleti (Oustalet's Chameleon) in South Florida
It is suggested that management for eradication of the species should include ongoing surveys, with removal efforts intensified from June to October, when females are known to be gravid.
Argentine Black and White Tegu (Salvator merianae) can survive the winter under semi-natural conditions well beyond their current invasive range
The survival and overall health of the majority of adult tegus in the study suggests weather and climate patterns are unlikely to prevent survival following introduction in many areas of the United States far from their current invasive range.
Diet of the Invasive Argentine Black and White Tegu in Central Florida
Abstract Salvator merianae (Argentine Black and White Tegu, hereafter also ABWT) is a large bodied, omnivorous lizard native to South America. In Florida, where the species was introduced via the pet
Brumation of Introduced Black and White Tegus, Tupinambis merianae (Squamata: Teiidae), in Southern Florida
The first observations of Black and White Tegu brumation in southeastern Florida are described after monitoring 5 free-ranging, adult male Black andWhite Tegus through an inactive season using radiotelemetry and automated cameras.
Invasive black spiny-tailed iguanas (Ctenosaura similis) on Gasparilla Island, Florida, USA.
It is suggested that shorter day length and colder temperatures create environmental conditions that are suboptimal for individual growth compared to those in the native range of Ctenosaura similis, except for the lack of large individuals.
Ecological Plasticity and the Future of the Argentine Giant Tegu (Salvator merianae Dumeril and Bibron, 1839) in the Southeastern US
It is found that the climate of the Southeast is amenable to the colonization of this vagile species, suggestive that a return to the strongly selected seasonal activity and gonadal cycles of central Argentina will accompany the Argentine Giant Tegu in its northward dispersal into more temperate conditions even as it retains a somewhat relaxed cycle in southern Florida.
Insights into the introduction history and population genetic dynamics of the Argentine black-and-white tegu (Salvator merianae) in Florida
Genotyping S. merianae from Hillsborough and Miami-Dade Counties at ten microsatellite loci indicates that both populations have low genetic diversity, and suggests that these populations underwent a bottleneck event prior to their divergence.
Evaluating Trap Alternatives for Removal of Salvator merianae (Black and White Tegu)
Alternative trap/lure combinations, such as traps made of PVC pipe baited with commercial mouse-based trap lure, might be just as effective at capturing Tegus, and thus could be less expensive options for Tegu control programs.


Survival of nests of the terecay turtle ( Podocnemis unifilis ) in the Nichare-Tawadu Rivers, Venezuela
The results indicate that humans are collecting eggs mostly from sites in which nests have the larger clutches and the higher potential hatching success, and sustainable yield programmes must consider where harvesting can take place and must avoid the application of standard harvests per nest.
The aggressive invasion of exotic reptiles in Florida with a focus on prominent species: A review
The situation in Florida is reviewed, including assessment of risk for management, and a subset of prominent species are used to illustrate in more detail the array of invasive reptile species circumstances in Florida, including routes of introduction, impacts, and potential and implemented management actions.
Verified non-indigenous amphibians and reptiles in Florida from 1863 through 2010: Outlining the invasion process and identifying invasion pathways and stages
Vouchers are used to confirm interceptions and introductions of all known non-indigenous amphibians and reptiles in Florida from 1863 through 2010, provide a list of these species along with their invasion pathways and current ecological status, and provide a species account for each newly confirmed species.
Dietary habits of the Burmese python, Python molurus bivittatus, in Everglades National Park, Florida
THE Burmese python (Python molurus bivittatus), a subspecies of the Indian python (Python molurus), is one of the largest snakes in the world, attaining lengths of up to six meters and over 90 kg in
Assessing the Potential Impact of Cane Toads on Australian Snakes
Overall, the analysis suggests that cane toads threaten populations of approximately 30% of terrestrial Australian snake species, with a similar low ability to tolerate toad toxins.
The Interplay Between Life History and Environmental Stochasticity: Implications for the Management of Exploited Lizard Populations
Monte Carlo simulations of different harvest strategies showed that estimates of population growth rates were overwhelmingly influenced by environmental variation and the number of years included in the growth rate estimate, even in the face of seemingly large changes in adult mortality that would result from population management.
Predicting establishment success for alien reptiles and amphibians: a role for climate matching
Findings may guide risk assessments for the import of live alien reptiles and amphibians to reduce the rate new species establish in the wild and improve climate matches between the jurisdiction where they were introduced and their geographic range elsewhere in the world.

A number of amphibians and reptiles have cyclic behavior, becoming inactive with the coming of the dry season, but some species of reptiles are active all year round.
Biologists are nearly unanimous in their belief that humanity is in the process of extirpating a significant portion of the earth's spe­ cies. The ways in which we are doing so reflect the magnitude
